Cause of death

Non traumatic intracerebral haemorrhage with further deterioration post medical intervention

AI-generated summary

Dorothy Simm, a 74-year-old woman, died from intracerebral haemorrhage with post-operative deterioration following participation in the EVACUATE trial at Monash Medical Centre. She presented with acute right parietal intracerebral haemorrhage and was consented for trial-protocol minimally invasive endoscopic evacuation. Intra-operatively, the surgeon encountered technical difficulties with the trial endoscope (poor visualization, suboptimal clot aspiration, frequent mirror cleaning) and likely entered the ventricular system. Post-operative imaging showed new intraventricular haemorrhage and hydrocephalus requiring external ventricular drain insertion. Despite appropriate management, Dorothy subsequently developed a new contralateral spontaneous intracerebral haemorrhage with very poor prognosis and died 9 days post-operatively. The coroner found the neurosurgical team acted reasonably and appropriately, the surgery did not cause her death, and her death could not have been prevented. However, the coroner criticized Monash Health for failing to assign an Incident Severity Rating (ISR) to this adverse patient safety event, recommending better education about distinction between death audit and adverse event reporting.

Contributing factors

  • technical difficulties with trial endoscope equipment (poor visualization, suboptimal clot aspiration)
  • likely entry into ventricular system during evacuation
  • new contralateral spontaneous intracerebral haemorrhage post-operatively
  • underlying severe bleeding pathology
  • intraventricular haemorrhage with hydrocephalus

Coroner's recommendations

  1. Director of Quality and Safety at Monash Health should educate Quality and Safety leads of each clinical unit about the difference between Riskman's death audit functionality and the Adverse Patient Safety Event functionality to ensure there is an appropriate reporting culture.
